In short, a domain name is a facade – a sequence of words that users enter in the address bar of browsers to visit your site, but which is not the actual address of your site on the web. Domain names are linked to Domain Name System (DNS) servers, which are used to translate numeric addresses (known as IP addresses or Internet Protocol addresses) into words. Each site you visit on the Net has a numeric IP address in addition to its name, which is the real address of the site on the Internet.
Usually, domain names are classified by their extensions, which are identifying codes for domain names. The three most popular types of Top Level Domains (TLDs) are domains that are not tied to any country:
.COM: Short for .commercial, which means commercial. Domain names with the .com extension are far more popular than other names in their popularity and can be purchased by any person or company.
.NET: Short for .network, which translates as a network. Originally this domain extension was created for technical websites. However, domains with this extension can be registered by anyone.
.ORG: Short for .organization, which means organization. Originally it was intended for non-profit organizations and other organizations that do not use the .com or .net extensions. Currently, a domain name with the .org extension can be registered by any person or company.
Domain names can be assigned using country-specific extensions. Each country has its own domain extension; Canada, for example, uses the .ca extension, and Japan – .jp. Most countries have special rules where it is described exactly who can register domain names using this extension and for what purpose; therefore, it is important to examine the subject before doing anything.
ALTERNATIVE DOMAIN NAMES The
Internet Assigned Names and Numbers Corporation (ICANN), the organization responsible for administering top-level domains across the globe, recently approved several new extensions that are not assigned to any particular country. Among them:
Each extension was created for use for certain purposes and is accompanied by certain restrictions. More detailed information about these top-level domains can be found at: http://www.icann.org/tlds/
OTHER DOMAIN EXTENSIONS
In the process of finding a suitable domain name, you can find sites that offer to use extensions such as .xxx, .free and .mp3. These are not real extensions and are not endorsed by ICANN; rather, their availability to the user is guaranteed by the software. Since ICANN did not endorse more than one of these extensions and, in addition, users who do not have the appropriate software cannot access sites with such names, these extensions should be used only for some secondary purposes.
Although .com, .net, and .org extensions are commonly heard and visible, they are not the only extensions available for use. From a functional point of view, country domains work as well as any top-level domain, and alternative extensions work just as well. Therefore, you should not use a mediocre top level domain when you can find the best one with a different extension.
